How can I access which environment is set in CodeIgniter?

Question

I am new to CodeIgniter. I have found that, in order to manage multiple environments, CodeIgniter uses the following function in index.php

define('ENVIRONMENT', 'development');

to define the environment.

My question is, how can I get which environment set at index.php inside my controllers?

Answer 1

In your index.php file, try something like this:

if ($_SERVER['HTTP_HOST'] == 'dev' || $_SERVER['HTTP_HOST'] == 'localhost')
{
    define('ENVIRONMENT', 'development');
}
elseif ($_SERVER['HTTP_HOST'] == 'staging.example.com')
{
    define('ENVIRONMENT', 'staging');
}
else
{
    define('ENVIRONMENT', 'production');
}

Obviously, set it up with values that make sense for you. However, this will set the ENVIRONMENT based on where the application is running, automatically.

Answer 2

ENVIRONMENT is defined in index.php that is pipeline of each CI application file, you can access anywhere e.g model, view, controller, library

echo ENVIRONMENT;
